With reference to accompanying drawing, the filter assemblies according to the present invention usually marked by reference number 1 comprises housing 2, housing 2 internally define fluid (normally air) for carrying contaminant particle A to be removed by passage 3.
Therefore, assembly 1 can be arranged in the pipe place of any atmosphere control system, air exchange system, ventilating system, heating system and similar system and the filtration that can be preset for air and decontamination, air be introduced in its expection for enclosure space before flow through pipe.
Therefore, housing 2 can be made up of tubular sleeve, can insert coaxially along pipe or be defined by a part for pipe itself.
According to the advantageous applications will mentioned once in a while in the continuation part of this description, housing 2 is instead box-shaped body, the exit of system such as such as those systems above-described can be arranged on, therefore force air be finally incorporated into outlet towards enclosure space before through passage 3 (it is in the inside of box-packed main body).
As mentioned in the early time; the fluid flowing through passage 3 is preferably air; but do not get rid of and use assembly 1 to filter dissimilar fluid, and be provided in the possibility that uses in the different application relative to those systems described concise and to the point in aforementioned paragraphs and therefore do not abandon the protection domain that requires herein.
Contaminant particle A to be removed can be that any type is (in its electricity and/or microbiological property and in the solid-state, liquid of its physics or gaseous state, and can be organic or inorganic), but according to the preferred application hereinafter will often mentioned, it is made up of (or being configured for the inorganic substances of carrier of this pollutant) organic pollution such as virus, bacterium, spore, mould, fungi and analog.
As can from accompanying drawing it is seen that, the conductive grid 4 of at least one perforation is arranged on the first cross-section of passage 3, keep negative potential (its value can also be variable in time and can select arbitrarily according to specific requirement) to emit electrons in passage 3, electronics therefore can with by impact and the contaminant particle A that the fluid that the grid 4 of boring a hole flows through passage 3 carries is combined simultaneously.
Therefore, contaminant particle A is given negative electrical charge, allows negative electrical charge to collect by means of at least one accumulation plate 5, and accumulation plate 5 keeps positive potential and in the disposed inboard of passage 3 in the downstream of grid 4.
Therefore, plate 5 easily can regularly remove the particles A cleaning out collection, prevents excessive buildup.
Should point out, assembly 1 can be provided with the accumulation plate 5 of any number, accumulation plate 5 is arranged in passage 3 according to different structures, the specific requirement of basis: such as, accompanying drawing proposes the constructive solution resorting to three accumulation plate 5 of arranging with plan-parallel structure along passage 3.
In addition, with further reference to accompanying drawing, the inwall of the housing 2 at two accumulation plate layout places in three accumulation plate 5 can cover (being therefore placed between wall and plate 5) with the cover layer 2a be made up of insulating materials.
In order to be beneficial to the particles A of collecting belt negative electrical charge, the contiguous accumulation plate of at least one deflecting element 65 (and preferably but not exclusively make towards accumulation plate 5) is arranged and keeps negative potential (alternatively, the value identical with the negative potential of grid 4) to produce electric field in the inner side of passage 3, the result caused is that particles A deflects towards accumulation plate 5.
The number being arranged in the deflecting element 6 of the inner side of passage 3 can also change arbitrarily and not abandon the protection domain that requires herein.In the accompanying drawings, in fact eight deflecting elements 6 are set along each passage 3, these eight deflecting elements 6 align in couples along four row be parallel to each other (raw), and (it is parallel to inwall and the accumulation plate 5 of housing 2, therefore towards accumulation plate 5, to make contaminant particle A deflect better and precipitate and therefore guarantee optimum).
According to the present invention, filter assemblies 1 comprises at least one conducting filament 7, conducting filament 7 towards and the respective hole 8 of contiguous grid 4.Silk 7 keeps negative potential (it can also equal the negative potential of grid 4 and/or deflecting element 6) to form specific electron emission source, this electron emission source just arrange (it actually passes through above-cited respective hole 8) at least partially in a fluid by district to guarantee to be combined with the contaminant particle A carried by this part.
Especially, filter assemblies 1 comprises at least one first conducting filament 7 and at least one second conducting filament 7, this at least one first conducting filament 7 is towards corresponding hole 8, be adjacent to corresponding hole 8 and be arranged in the downstream of grid 4 substantially, this at least one second conducting filament 7, towards corresponding hole 8, is adjacent to corresponding hole 8 and is arranged in the upstream of grid 4 substantially.
Therefore, at least one 7 only downstream being arranged in grid 4 (or only upstream) constructive solution (as Fig. 1,2 and 3 embodiment in) and at least one 7 be arranged in the upstream of grid 4 and at least one 7 (preferably) constructive solution being arranged in the downstream of grid 4 (as Fig. 4,5 and 6 embodiment in) in the protection domain that therefore requires herein.
Therefore, usefully, the constructive modification being described in detail in all propositions in the continuation part of this description is understood to be thought of as (even not pointed out clearly) not only to have been had the silk 7 in the only downstream (or only upstream) being arranged in grid 4 but also had had the silk 7 (guaranteeing the solution of most high filtration effect) of both the upstream and downstreams being arranged in grid 4.
Especially, assembly 1 comprises multiple silk 7 (number is selected arbitrarily and therefore do not abandon the protection domain that requires herein), multiple silk 7 towards and at least one corresponding hole 8 of contiguous grid 4.Each silk 7 keeps predetermined negative potential so that electron emission, and electronics can combine to by the contaminant particle A at least carried through the fluid in corresponding hole 8.
Even more accurately, each hole 8 of grid 4 towards and contiguous multiple silk 7, multiple silk 7 keeps predetermined negative potential.
By this way, the electronics launched by grid 4 concentrates on silk 7, and because silk 7 towards the fluid of all-mass be forced to through hole 8, so very high effect guaranteed by assembly 1 according to the present invention, because the transmitting that fluid stream passes wherein electronics is the highest region, therefore guarantee that electronics is attached to very a large amount of contaminant particle A.
Expediently, each silk 7 has different length and preferably (but not exclusively) is selected as multipole type and is made up of metal material.
According to the preferred constructive solution that the non-limiting example applied by means of the present invention is quoted, each silk 7 is coupled to grid 4 with its first stiff end 7a.As shown in figures 3 and 6, at opposite end place, each silk 7 has the second free end 7b, and the second free end 7b is wedge shape to define the structure (it is outwards tapered) of point substantially, and the result caused is the further increase of electron emission.
Expediently, filter assemblies 1 comprises at least one unit 9 and is comprised in organic pollution such as virus, bacterium, spore, mould, fungi and analog in the contaminant particle A carried by fluid for deactivation.Unit 9 towards and contiguous accumulation plate 5 to cause pollutant harmless.In addition, should point out, the unit 9 (such as, as be two in the accompanying drawings) of arbitrary number can be arranged along passage 3.
Since people do not wish regularly to remove accumulation plate 5, the existence of unit 9 guarantees that the organic contamination composition granule A be collected on plate 5 can not breed and instead make the organic contamination composition granule A be collected on plate 5 be completely harmless.Therefore, it is not biological contamination source to people and harmful source that organic contamination composition granule A and plate 5 any is separated in being introduced in the enclosure space in downstream of potential generation subsequently.
Especially, according to possible constructive solution, deactivation unit 9 is made up of UV radiation sterilization lamp substantially, towards and contiguous accumulation plate 5 for its continuous print radiation, the result caused is the deactivation of the microorganism of any type of no matter inactivation time.
According to the constructive solution of the suitable practical significance that the non-limiting example applied by means of the present invention proposes, each hole 8 is automatic adjustment and is crossed by diameter rib 10.Towards and the first end 7a of all silks 7 in contiguous identical respective hole 8 is stably coupled to the center of rib 10 substantially, such as, shown in Fig. 3 and 6.
Expediently, assembly 1 according to the present invention comprises at least one reference frame (reference frame), this at least one reference frame adjacent bores 8 is arranged and is kept the current potential different relative to the current potential of silk 7, and preferably keeps the current potential equaling earthing potential.By this way, in the inner side of passage 3 and more accurately between plate 5 and framework, can produce and to be launched by silk 7 and in fact by the electron stream that framework attracts, it is directed along predetermined direction.
According to the possible embodiment that the non-limiting example applied by means of the present invention proposes in figures 7 and 8, the framework preferably equaling the current potential of earthing potential is kept to be made up of emulsion sheet 11 substantially, emulsion sheet 11 is made up of metal material (such as copper), and (so that partly or according to preferred solution fully grating 4) is arranged in the face at least pointing to accumulation plate 5 along grid 4.
By this way, launched by silk 7 and the given a kind of track of electronics attracted by sheet 11, this track has (initial part) at least partially of the direction of advance being essentially perpendicular to fluid, because electronics is discharged by the free end 7b of silk 7, and fall substantially in plane that the grid 4 that is in fact positioned at by sheet 11 defines.
But, if do not have to get rid of in silk 7 downstream that is arranged in grid 4 and upstream (as described in front page), then respective sheet 11 is arranged in the possibility on each of grid 4.
According to different embodiments, the framework that maintenance as already mentioned preferably equals the current potential of earthing potential is made up of screening substantially, is parallel to grid 4 and near grid 4, arranges to attract the electronics launched by silk 7.
If silk 7 is arranged in only downstream or the only upstream of grid 4, screening correspondingly can be arranged in only downstream or the only upstream of grid 4.If instead, silk is arranged in downstream and the upstream of grid 4, then use the assembly 1 being provided with single screening or two screenings of upstream and downstream being arranged in grid 4 easily of use.
According to the other embodiments shown in by means of the non-limiting example in Fig. 9 and 10, the hole 8 of each automatic adjustment is provided with circumference flange (lip) 12, circumference flange 12 has the shape of generic cylindrical and to extend from the edge (rim) in hole 8 at a right angle with grid 4, and can point to accumulation plate 5 and/or contrary reverse (depending on the layout of silk 7).In this embodiment, keep the framework preferably equaling the current potential of earthing potential to be made up of the cover layer (by metal material preferably copper one-tenth) at the top of each bead 12, size is suitably set to extend axially beyond the free end 7b of silk 7.
By this way, launched by silk 7 (and especially by its free end 7b) and be prompted to follow the track with (initial part) at least partially that be substantially parallel to fluid direction of advance by the electronics that bead 12 attracts, guarantee that electron stream has fractional orbital consistent with fluid stream substantially, extend electronics can carry out contacting the period continued with the contaminant particle A carried by air, be beneficial to it and combine.
According to embodiment possible in addition, hole 8 has hexagonal shape (but also can provide the assembly 1 being provided with difform hole 8) substantially: leg-of-mutton auricle (tab) is given prominence to (defining the outward appearance of the bastard file (grater) for grid 4) and pointed to accumulation plate 5 and/or away from accumulation plate 5 from each side of the hexagonal perimeter in hole 8 substantially.
So reference frame is towards hole 8 and keep the current potential different relative to the current potential of silk 7, and preferably keep the current potential equaling earthing potential to be launched and the electron stream attracted by framework by silk 7 and auricle to produce, it is directed along predetermined direction.In this embodiment, framework can be preferably made up of the framework of wire netting trellis, arranges with the parallel downstream (and/or its upstream) being configured in grid 4 and near grid 4.
In addition, should point out, the assembly 1 with ion generator can be provided, ion generator be positioned at substantially passage 3 end section, be therefore positioned at the exit that air leaves assembly 1, be suitable for rebalancing and be present in negative electrical charge in air.
In addition, as can it is seen that assembly 1 according to the present invention can comprise for supporting deflecting element 6 and the instrument 13 making deflecting element 6 be shaped from accompanying drawing.
As follows according to the operation of assembly of the present invention.
Assembly 1 as already mentioned can along also having the system of ventilation, climate controlling etc. of any means of transport (aircraft, train, ship, military vehicle, spacecraft and other instruments) and the pipe of equipment for any enclosure space (civil construction (civil), hospital and analog) or installing in exit, to protect the health of people.In addition, in medical science and hospital field, assembly 1 can also be used for isolating single berth in epiphytotics situation.
Under any circumstance, the application no matter expected (be included and be in or be not in concise and to the point those application described above), air (or other fluids) to be filtered is through passage 3 (being included in substantially accumulation plate 5 and deflecting element 6) and be defined at the inner side of housing 2.
In more detail, the air of all-mass passes the hole 8 of grid 4 and then impacts silk 7, silk 7 scattered electron (because grid 4 and silk 7 keep negative potential).Therefore electronics (optionally pointed to reference frame expediently, reference frame preferably keeps earthing potential) can be combined with contaminant particle A, gives its negative electrical charge.
Then accumulation plate 5 is suitably arranged in the downstream of grid 4 and the contaminant particle A by keeping positive potential to carry out suction band negative electrical charge, therefore from air, removes contaminant particle A.
In order to be beneficial to such result, the contiguous accumulation plate 5 of deflecting element 6 is arranged, and contributes to producing the electric field being beneficial to and being collected in by contaminant particle A on plate 5.
Maximum filter efficiency is guaranteed in the selection resorting to the silk 7 being arranged in the hole 8 of being crossed by fluid stream, produce the high scattering of electronics and electronics concentrated on around in the region of the free end 7b (in fact it crossed by fluid stream) of silk 7, therefore guarantee combination between a large amount of electronics and contaminant particle A (and therefore occur thereupon downstream by electron collection on plate 5).
In fact, constructively select the filtration efficiency obtained also to make to remove ultrafine dust from fluid stream and therefore remove undersized even especially contaminant particle A (usually the most dangerous to people) such as there is the size that is less than 0.3 μm and the contaminant particle of being down to nano-grade size becomes possibility by means of above-described.
In addition, the existence of bactericidal lamp (or other deactivation unit 9) makes to cause it to be that harmless (and avoiding it to breed) becomes possibility by eliminating organic pollution, this allows the maintenance with finite frequency to get involved, such as even just annually.
Also by entrust in field effect in fact filtering and the selection of the engineering properties of nonporous membrane (as occurred when using conventional filters) provide to the contribution of result: when not keeping in repair, in fact the latter stands the progressive obstruction of hole, along with the minimizing of consequential filtering efficacy.Vice versa, makes contaminant particle A electronegative and the frequency influence cleaning and keep in repair that its ability be collected in accumulation plate 5 is not carried out thereon.
In addition, it should be noted, assembly 1 not to air by occur obvious resistance and therefore start time the material of any kind is not discharged in enclosure space by it, because contaminant particle A is retained on plate 5.In addition, such result allows little (and very simple) maintenance get involved and therefore do not endanger filtering efficacy (even when not carrying out any maintenance and/or it being entrusted in unskilled workers, also keeping filtering efficacy to be maximum).
In practice, it has been found that, the object of expecting is realized completely according to assembly of the present invention, because towards and the existence being kept at least one conducting filament of negative potential in the respective hole of contiguous grid is beneficial to the electronics launched by silk and being combined at least partially of fluid to be filtered of passing hole, guarantee the high filtration effect of assembly.
Therefore, the present invention of imagination allows a large amount of amendments and modification, and all amendments and modification are within the scope of the appended claims.In addition, all details can be replaced with element equivalent in other technologies.
Such as, do not get rid of the possibility provided by the assembly 1 of the pipe along system or the multiple module compositions in exit arranged in series, wherein each module has the element that describes in front page and therefore has at least one grid 4, at least one accumulation plate 5 and at least one deflecting element 6.
By this way, the total effect according to assembly 1 of the present invention can be increased further, make air keep with limited speed through passage 3 (another factor of maximum filtering can be guaranteed) simultaneously.
In the embodiment of the embodiment illustrated, in fact mutually can exchange from the different feature existed in other embodiments in embodiment relating in specific embodiment the single feature provided.
In practice, the material of use and size can be arbitrary with the state of the art as requested.
